Well i got a D16Y8 in my Brothers ef 1991 STD model, when we got it in and running its only running on 3 cylinders we have compression, injectors are firing and getting spark. We have tried new spark plugs, new wires, new rotor button and cap different dizzy and not running a Vtec Ecu different injectors, correct firing order, all valves are working and no matter what we do the number 2 cylinder will not fire.
 
yep its factory spec with the other ones. the only variable left is air and the only way to check that is takin off the intake mani and makin sure nothin is blockin it. does any body think that is possible.
